Bf Skinner Free Will Summary

Lauren Slater is the author of the 2004 book called “Opening Skinner’s Box”. In this book, Slater writes about ten important psychological studies of the 20th century and she describes the personalities of the famous researchers who conducted the experiments. The book is written in story form with the author recreating the experiments in her own way. Slater uses the experiments to get the reader thinking about important concepts such as free will, authoritarianism, conformity, and morality. She writes about controversies that surround the researchers and she also tries to track down the actual researcher or other people who can help provide more information. In the first chapter of the book, Slater writes about the work of B.F. Skinner, who is known for his contribution to behavioral psychology, specifically the concept of operant conditioning. In this paper, I will summarize some of the major points from this chapter, titled “Opening Skinner’s Box” and I will also offer a critical analysis of the chapter.

B.F Skinner was an American Psychologist who invented the operant conditioning chamber. The chamber he set up had rats in it and a lever, once the rats pulled the lever they were given a piece of food. After this happened the rate of bar pressing would increase dramatically and remain high until the rat was no longer hungry. He was a firm believer of the idea that human free will was actually an illusion and any human

Thereby, Skinner produced experiments whereby rats would navigate through mazes to achieve the goal of a box containing food. His interest was the behaviour of the rat, taking the right turn to achieve the desired result, food. To begin with the rats would take the wrong turn but with experience, they became more skilful. The rats learning behaviour was measured in two ways, firstly the length of time it took from start to end and secondly, the reduction in errors. This was a lengthy experiment which led Skinner to produce ‘the Skinner box’. Whereby, rats learnt to press a lever and pigeons learnt to peck a key in order to attain food, also known as behaviour shaping. This experiment lacks ecological validity as the animals are kept in a controlled environment which is dissimilar to their natural habitat. However, the results which were attained could not have been possible in natural circumstances. Skinner wanted to observe if behaviour could be learned through reaching a desired outcome such as positive reinforcement which needed to be

Skinner created the theory of Operant Conditioning as he believed that all behaviour can be controlled by rewards or reinforcement. This is very different from Pavlovs theory of Classical Conditioning as Skinner is trying to control voluntary behaviour. This is done by giving the subject a positive or negative reaction to an action with the theory that a negative response will discourage the subject to repeat the action. A good example of this is house training a dog, as the dogs natural reaction is to relieve itself, however it must be taught to wait until it is outside. The more the dog waits until he is outside, the more praise he receives therefore it is less likely to wish to instigate a negative reaction by relieving himself inside the house.

A question Skinner had to deal with was how we get to more complex sorts of behaviors. He responded with the idea of shaping, or “the method of successive approximations.” Basically, it involves first reinforcing a behavior only vaguely similar to the one desired. Once that is established, you look out for variations that come a little closer to what you want, and so on, until you have the animal performing a behavior that would never show up in ordinary life. Skinner and his students have been quite successful in teaching simple animals to do some quite extraordinary things.

A researcher named Burrhus Frederic Skinner thought he would develop the idea of operant conditioning. He suggested than we act in regard to consequences (reward or punishment) in which we actively learn. He suggested there are 3 types of these consequences of behavior; positive reinforcement, negative reinforcement and punishment. Positive reinforcement is receiving a reward for acting in a certain way. An example of this could be getting a school prize for performing well in your exams, because of the reinforcement of the prize, the student will try to perform well every time. Negative reinforcement occurs when we act in a way that avoids an unpleasant consequence (e.g. not being late to a meeting because you do not want to be perceived as rude). Punishment is an unpleasant consequence that comes from the way we act. For example, gaining a detention for arriving late to lessons. Punishment decreases like probability that behaviour is likely to be repeated. Whereas, in positive and negative reinforcement the chances are you will repeat the behaviour. Skinner’s conducted research in the form of a lab experiment. He used a hungry rat that was placed in a cage that had been especially developed for the purpose of the study and was named Skinner’s box. In the cage was a button and a food dispenser. When the rat pressed the button food would appear in the dispenser. The animal soon learned that

Through the use of this model, Skinner was able to develop a more comprehensive view of conditioning which is now known as operate conditioning. Operate conditioning is rewarding a desired behavior. Skinner performed much research on this new form of conditioning and arrived at the conclusion that both animals and humans would repeat actions which led to favorable outcomes as well as suppress those that produced an unfavorable outcome.

Skinner (1948) was also influenced by Thorndike’s (1898) operant conditioning of cats and went on to use similar techniques to study conditioning in rats. Skinner studied how behaviour that is rewarded will be repeated, unlike behaviour that has a negative consequence. Skinner (1948) placed hungry rats in a ‘skinner box’ with a lever, when the lever was pressed, food was released and the rats soon learned that when they pressed the lever they would be rewarded. Skinner (1948) then placed rats in another box and administered them with an electric current. If the rats pressed the lever in this box it would stop the discomfort of the current. After repeating the rats quickly learnt to press the lever. Skinner (1948) argued that all human behaviour can be learned through operant conditioning (McLeod 2015).

Using squirrels he began to use a reward system to train them, noticing that the squirrels can relate doing one form of action to get a treat. This experiment proved very promising and went onto applying the same training techniques to other animals and

Skinner conducted a series of research experiments with rats and pigeons under controlled laboratory conditions using a specially designed cage. By doing so he sought to demonstrate that behaviour can be created and reinforced by external factors. The puzzle box he created for his experiments has become so widely used that it is now known as the “Skinner box”. Animals would be placed in a cage which had a bar lever mechanism used to dispense food; Skinner would measure the frequency of the bar pressing and introduce different variables into the experiments. This led to his discovery of 'partial reinforcement' and its correlation to the slower extinction of shaped behaviour. When food pellets would only be dispensed once in a while (as opposed to every pressing) Skinner noticed that it took longer for the learnt behaviour to become extinct. The powerful phenomenon of partial reinforcement can be noticed in gambling establishments; a player on a slot machine is more likely to keep up their behaviour of playing if the rewards are unpredictable and occasional. The player becomes more persistent in their gambling in the hope that the next coin will be the winner (Hunt, 1993).

According to Gewirtz and Peláez-Nogueras (1992), “B. F. Skinner contributed a great deal to advancing an understanding of basic psychological processes and to the applications of science-based interventions to problems of individual and social importance.” He contributed to “human and nonhuman behavior, including human behavioral development, and to various segments of the life span, including human infancy” (p. 1411). One of Skinner's greatest scientific discoveries was “single reinforcement” which became sufficient for “operant conditioning, the role of extinction in the discovery of intermittent schedules, the development of the method of shaping by successive approximation, and Skinner's break with and rejection of stimulus-response

the “Skinner box”. He found that he was able to train rats to press a

He also read about animals. He collected toads, lizards, and snakes. He trained pigeons to do tricks after he saw them performing one year at a fair. Training the pigeons probably was where he got his ideas of operant conditioning. He attended Susquehanna High School just like his mother and father. In his graduating class there were only eight people including him. He was a very intellectual person. He reported that he really enjoyed school. Over the four years in high school Skinner became good at math and reading Latin, but was no good at science. He was always performing physical and chemical experiments while he was at home. His father was a book collector. Skinner always had a good library of books around his house. Skinner recalled the little collection of applied psychology journals that his father had bought. Those books could have been the starting point in his psychology career. Skinner grew up in a very religious family.

While other psychologists believed that human psychology is a complex system because there are so many external influences, Skinner had believed that human’s mind is the same as other animals, which explains why he had done experiments using pigeons. Inspired by Watson and Pavlov, Skinner decided to study psychology and focused on behaviorism. Skinner’s theory was based on self-observation, which made him stood onto his believes regardless of the oppositions. In fact, during WW II, “Skinner convinced the military to fund his research--the famous Project Pigeon--to train pigeons to guide bombs and torpedoes.” (Greengrass, pg, 80) He chose pigeons because he thinks they live

Skinner is one of the very first renowned behaviorists that came up with classical conditioning on organisms and on top of this, other experiments were also built like the operant conditioning experiments. The process of classical conditioning works with the introduction of neutral stimuli before the original stimulus and the same reaction is elicited from the organism even without the presence of the original stimulus. For instance in the instance of the Pavlov dog, it salivated with every sight of food as the original stimulus for the salivation. When a neutral stimulus was introduced like a bell that was rang each time before it was fed, the dog started salivating at the ringing of the bell even before the food was availed. Another famous experiment was of the Skinner box where caged animal detected that by pushing a given button or lever, food could roll into the cage. The voluntary action preceded the stimulus.
